An injection teaches the body's own defenders to hunt diseased cells

At MIT, engineers Daniel Anderson, Robert Langer and their team found a way to reprogram natural killer cells — the immune system's patrol cells — while they are still inside the body, using tiny fat particles to deliver instructions. The approach, published in Nature Biotechnology, could one day treat some cancers and autoimmune diseases without the slow, costly step of rebuilding a patient's cells in a lab.
